| 目的 实现功能磁共振成像与扩散张量成像的图像融合。方法 运用事件相关功能磁共振成像技术,获得10名健康志愿者手指运动过程中大脑皮层功能图像,运用扩散张量成像技术获得初级运动区和辅助运动区的下行纤维束的图像,采用AFNI、FSL和AMIDE 三种国际上通用的免费磁共振分析软件对图像进行融合。结果 采用该方法可获得脑激活、纤维束和脑解剖的融合图像,初级运动区、辅助运动区的激活模式及其下行的纤维束可同时在个体和成组脑结构上清晰显示。结论 应用通用免费磁共振分析软件可以实现功能磁共振成像与扩散张量图像的融合,可望为临床诊断和脑功能基础研究提供了新的途径。 |

| Objective To fuse the images of blood oxygen level dependent (BOLD-fMRI) and diffusion tensor imaging (DTI). Methods Event-related fMRI and DTI were performed in 10 health volunteers at a 1.5T MR scanner. Images data were processed with combination of AFNI, FSL and AMIDE, the three most commonly used software packages. Results High quality fusion images of fMRI and DTI were obtained, in which activation in the primary motor cortex and the supplementary motor area, and corticofugal fibers originated from them were clearly visible in the same individual and group brain. Conclusion Fusion images of fMRI and DTI can be reliably generated by commonly used free software packages This method can provide a new promising tool for both clinical diagnosis and basic research of human brain function. |
